A Statistical Test Suite for Random and Pseudorandom Number Generators for Cryptographic Applications
This paper discusses some aspects of selecting and testing random and pseudorandom number generators. The outputs of such generators may be used in many cryptographic applications, such as the generation of key material. Generators suitable for use in
Simulation Model for the IEEE 802.15.3/3b WPAN Standard
The1IEEE 802.15.3 is an emerging technology for high data rate wireless multimedia applications in Wireless Personal Area Networks (WPAN). In this paper, a discrete event simulation model has been implemented using OPNET2 Modeler to simulate the essential
Editorial: Message From the Outgoing Editors
Some four years ago, we took the responsibility for editing this TRANSACTIONS. Our editorial duties have now ended. It has been a privilege and honor to serve our readers and our authors.
PYRAMID MODEL BASED DOWN-SAMPLING FOR IMAGE INPAINTING
Image inpainting is a useful and powerful technique for automatically restoring or removing objects in films and damaged pictures. In the last ten years, many excellent inpainting algorithms have been proposed after Bertalmio et al. [1]. However, no paper
A Channel Propagation Model for the 700 MHz Band
Conversion from analog television in the United States combined with the appeal for broadband public safety communications is generating a lot of interest in the so-called 700 MHz band between 698-806 MHz. To our knowledge, no channel propagation model for
Introduction: Cybersecurity
Enterprise security, often considered a burden for system administrators and users alike, is one of the most rapidly evolving areas of IT. The articles in this issue can help IT professionals who want to be intelligent providers or consumers of secure
Guidelines for Smart Grid Cyber Security
[Superseded by NISTIR 7628 Rev. 1 (Sep. 2014), http://www.nist.gov/manuscript-publication-search.cfm?pub_id=916068 ] Smart Grid technologies will introduce millions of new intelligent components to the electric grid that communicate in much more advanced
Framework for Emergency Response Officials (ERO): Authentication and Authorization Infrastructure
This document describe a framework (with the acronym ERO-AA) for establishing an infrastructure for authentication and authorization of Emergency Response officials (ERO) who respond to various types of man-made and natural disasters. The population of

Specification of Attribute Relations for Access Control Policies and Constraints Using Policy Machine
Attribute relations in access control mechanisms or languages allow accurate and efficient specification of some popular access control models. However, most of the access control systems including today s de-facto access control protocol and specification
Practical Near-Collisions for Reduced Round Blake, Fugue, Hamsi and JH
A hash function is near-collision resistant, if it is hard to find two messages with hash values that differ in only small number of bits. In this study, we used hill climbing methods to find near-collisions for some of the second round SHA-3 candidates
Assessing the Effectiveness of Security Controls in Federal Information Systems
This bulletin summarizes the information presented in NIST Special Publication (SP) 800-53A, Revision 1, Guide for Assessing the Security Controls in Federal Information Systems and Organizations: Building Effective Security Assessment Plans. The revised

A Flexible and Efficient Numerical Framework for Image Segmentation by Energy Minimization
A widely used approach to image segmentation is to define corresponding segmentation energies and to compute shapes that are minimizers of these energies. In this work, we introduce a flexible and efficient numerical framework for minimization of such
Recommended practice extensions for GD&T in STEP-AP210 in the context of electronic connectors
The purpose of this document is to extend the recommended practices for the representation of GD&T in STEP AP 210 (ISO-10303:210) in the context of packaged electronic connectors. Geometric dimensioning and tolerancing (GD&T) is critical to the design
Conductive Carbon Nanotubes for Semiconductor Metrology
This paper presents an evaluation of e-beam assisted deposition and welding of conductive carbon nanotube (c-CNT) tips for electrical scanning probe microscope measurements. Variations in CNT tip conductivity and contact resistance during fabrication were

Message Recovery and Pseudo-Preimage Attacks on the Compression Function of Hamsi-256
Hamsi is one of the second round candidates of the SHA-3 competition. In this study, we present non-random differential properties for the compression function of Hamsi-256. Based on these properties, we first demonstrate a distinguishing attack that

Multimode Fiber Launch Study: Estimating the Impact on Measurements of Delay
The purpose of this study was to evaluate measurement uncertainties introduced into time delay calibrations of multimode fiber reference spools. While the principles described are generally applicable, the results could be different for other types of
REFLECTIVITY STUDIES OF PASSIVE MICROWAVE CALIBRATION TARGETS AND ABSORPTIVE MATERIALS
We report the characterization of blackbody reflections as a part of the recent progress on the development of brightness standards for microwave remote sensing at National Institute of Standards and Technology (NIST).Three blackbody targets at variable
Non-Coherent Amplify-and-Forward Generalized Likelihood Ratio Test Receiver
This paper proposes a simple non-coherent amplify-and-forward receiver for the relay channel and evaluates its diversity performance for Rayleigh fading channels. We use the generalized likelihood ratio test to obtain the decision rule in closed form
Examining the True Effectiveness of Loading a Reverberation Chamber
In this paper we explore how placing the same amount of absorber in different locations within a reverberation chamber can have different loading effects. This difference can have a significant impact on measurement reproducibility, both for measurements
